Transhumanist thought aims to transform human nature through technology, science, and philosophy. Ray Kurzweil’s works occupy a notable position within contemporary philosophical discourse, particularly through his assertions concerning the relationship between consciousness, mind, and artificial intelligence. The purpose of this research is to examine how Kurzweil redefines the concepts of mind, consciousness, and self within the framework of transhumanist philosophy, and to analyze the place of this conceptual transformation within contemporary philosophy of mind. Kurzweil’s conception of the human being as an algorithmic, digitizable, and reproducible pattern of consciousness presents an alternative paradigm to the classical understanding of humanity. In this context, the study aims to philosophically analyze how the mental and existential structure of the human being is transformed through key transhumanist concepts such as technological singularity, mind uploading, and cybernetic immortality. This research adopts a qualitative approach, systematically employing document analysis to examine Kurzweil’s works on transhumanism. The primary data consists of Kurzweil’s major texts in which he constructs his transhumanist thought. His ideas are explored through both descriptive and interpretive frameworks, and technical content is integrated with philosophical discussion. The significance of this study lies in its treatment of transhumanism not merely as a technological trend, but as a philosophical orientation that reconfigures the mental and existential boundaries of the human. In particular, Kurzweil’s attempt to transform fundamental issues such as consciousness, identity, and death through technical means is evaluated as a set of original responses to classical philosophical questions, articulated in the scientific language of the age. Accordingly, this research opens a critical discussion on a new conception of humanity that transcends traditional assumptions about human nature and builds a theoretical bridge between philosophy of mind and philosophy of technology. In conclusion, the study reveals that Kurzweil conceives the human being as a data-based pattern of consciousness; that the self can be reduced to a portable and reproducible structure independent of its physical substrate; and that death can be redefined as the loss of information. This approach allows for the conceptualization of the human not merely as a biological entity, but as a subject capable of algorithmic self-replication and digital continuation. Thus, Kurzweil’s transhumanist ontology philosophically outlines the limits of post-human existence, inviting a rethinking of foundational concepts such as consciousness, selfhood, and identity in light of the possibilities afforded by the digital age.
